RESILIENT WHEEL.

Application filed January 14, 1915.

To all whom it may concern Be it known that we, HARRY I. CHEW and WALTER S. SERG-EANT, citizens of the United States of America, residing at Washington, in the District of Columbia, have invented certain new and useful. Improvements in Re silient l/Vheels, of which the following is a specification.

The present invention relates to resilient wheels of the type wherein the cushioning element located at the hub, allows of relative movement between the hub and wheel rim, and has for'its purpose to provide a means for locking or holding the hub and rim against relative motion when the wheel is used on gun carriages for the obvious purpose of maintaining stability during firing at all angles of terrain or elevation.

The disclosure herein is designed with especial reference to the construction of re silient wheel shown in our co-pending applications for U. S. patents Serial Numbers 839,521; 848,018 now Patent No. 1,149,425. patented Aug. 10, 1915; and 854.988 respectively dated May 18 1914; June 29, 1914: and August 4, 1914.

The invention further contemplates the employment of the locking feature on the wheel. as ordinarily used, as an emergency expedient in the event of breakage of the resilient support or for other cause.

The construction is shown by Way of illustration in the accompanying drawings wherein:

Figure 1 is a central vertical sectional view of a resilient wheel embodying the locking features, taken on the line 1-1 of Fig. 2. Fig. 2 is a transverse sectional view of the same with the lock actuating device omitted. Fig. 3 is a side elevation of the locking ring. Fig. 4 is an edge view of the same partly broken away for clearness. Fig. 5 is a detailed view of one form of suitable device for actuating the locking ring, taken on the line 55 of Fig. 6. and Fig. 6 is a front view of the same.

Referring to the construction in further detail and wherein like characters of reference indicate corresponding parts in the different views shown 3 designates the inner rim portion of the wheel and which at the center is in the form of a disk 4, and which disk together with said rim portion will Specification of Letters Patent.

Serial No. 2,224.

hereinafter be referred to as the rim of the wheel.

The wheel hub comprises two members, or parts 5 and 6 which are mounted on the axle (not shown), and are constructed with slde plates 8 and 9 respectively. The mem bers 5 and 6 are suitably connected by a reduced and threaded portion 5 on the part engaging with threads formed on the inner end of the part 6 (see Fig. 2). The plates 8 and 9 are formed with inturned edges 8" and 9 disposed to have free contact or engagement with the opposite faces of the rigid rim portion 4:, as clearly shown in Fig. 2 Said hub plates 8 and 9 are substantially of concave-convex design in cross-section and form a substantially complete inclosure or housing for the wheel resilient elements contained therein.

A pair of telescoping sleeves 15 and 16 are mounted to have axial movement on the hub sections 5 and 6 within the housing and said sleeves are formed with cone heads 17 and 18. The conical surfaces of said cone heads bear in contact with the relatively angular faces formed on the rim 4:, and a spring 2.1 surrounding the sleeves engages against a collar or nut 22 secured on the free end of the sleeve 15, and against the cone-head 18 of the sleeve 16 and thereby forms a floating suspension or bearing for the wheel rim after the manner described in our co-pendapplications above referred to.

The flexible connection between the rim and hub consists of a floating ring 59 arranged concentric with the axis of the hub and secured to said rim by a pair of diametrically opposite links 60 having pivotal engagement with the ring and rim by pintles 62 and 63; and a similar pair of links ()1 connect said rim with the hub plate 8. The links 61 have pintle engagement at 6-1 and 65 with said ring and hub plate as in the former instance.

A suitable device for locking the rim and hub against relative motion in the event of breakage of any of the rim sustaining elements or for other cause. consists of a pair of annular flanges 66 and 67 mounted on the hub plate 9 and providing an annular chamber or recess receiving a ring 68 having a beveled or reduced edge 69 designed to engage within a complementary formed recess in the adjacent face of the rim 4: asin the manner shown in Fig. 2.

The means for axially moving the locking ring to engage with the rim consists of a plurality of wedge elements comprising spiral flanges 71 formed on the perimeter of the ring and fitting within corresponding channelways 72 formed on the inner periphcry of the flange 67.

A shaft 73 has suitable bearing in the flange and side plate (66 and 9), and carries a pinion 74 in mesh with a rack 7 5 formed on the inner face of the ring 68, and said rack and pinion effect translation of the locking ring as will be obvious.

A lever or crank 76 is secured to the square end 77 of the shaft 73 and normally holds the locking ring against motion through acotter pin 78 on the lugs 79 suitably formed on the hub plate 9. The lever 76 is bowed and in either of its extreme positions fits within apertures formed in the hub plate as shown. To rotate the shaft 73- the lever is withdrawn by removing the locking pin when said shaft may be turned through an angle of 180 when it may be again locked by transferring the pin 7 8. The respective positions of the lever are shown and indicated in Fig. 5.

It will be obvious of course that differ ent forms of construction may be provided in lieu of that disclosed and described herein. And while we have shown and described certain apparatus for accomplishing the result initially stated it is to be understood that we are not limited to the precise details shown but may on the other hand adopt such modifications or changes within the scope of the claims to better suit'the end in view.

lvVhat is claimed as new is:

1. The combination with a resilient wheel having arelatively movable hub and rim, of an axially movable member providing a locking device therebetween; and means for actuating said movable member comprising wedge elements on the hub.

2. The combination with a resilient wheel having a relatively movable hub and rim, of an axially movable member providing a locking device therebetween; and means for actuatingsaid movable member comprising complementary wedge elements on said member and the hub.

3. The combination with a resilient wheel having a relatively movable hub and rim, of an axially movable wedge member providing a locking device therebetween; and a rack and pinion for actuating said movable member.

4:. The combination with a resilient wheel having a relatively movable hub and rim portion, of a ring carried by the hub and axially and circumferentially movable to engage the rim portion and provide a locking device therebetween, substantially as described.

5. The combination with a resilient wheel having a relatively movable hub and rim portion, and said rim portion having an annular channel; of a ring carried by the hub and axially and circumferentially movable to engage the rim channel and provide alocking device between. the hub and rim portion substantially as described.

6. The combination with a resilient wheel having a rim portion formed with a channel and a relatively movable hub having a side plate formed with a flange. of a ring mounted on said flange and movable to engage said channel and provide a locking device between the hub and rim portion, substantially as described.

7. In a resilient wheel the combination of a hub having side plates; :1. floatingly mounted rim portion; a flexible connection be tween said rim and one of the side plates; and a locking ring carried by the other side plate and adapted to engage with said rim portion; substantially as described.

8. In a resilient wheel the combination of a rigid rim portion; a hub having side plates engaging the rim portion and providing a housing; resilient elements sustaining the rim; a flexible connection between said rim and one of the side plates; and a locking ring carried by the other side plate and adapted to engage with said rim portion, said connection and the locking ring located wholly within the housing, substantially as described.

In testimony whereof we afiix our signatures in presence of two witnesses.
